How can increase my coder skills?

Question

On my profile skills I have 0% at coder. I am not in a hurry but I am wondering: How can I become coder?

Answer 1

For every code with 5 upvotes or more you get 2%

Answer 2

Practice makes perfect concentration is the solution to your question

Answer 3

I learn for myself, I am not in a competition with somebody. I want to learn and to check my status from time to time and see a little progress there.
Must somebody else vote the programs and so will rise coder status above 0%?
There is no problem if I have still 0% next month, I just want to know what must somebody do to have in status more than 0% next to coder.
